CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 5 DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: April 23, 2026 TO: Pre-Application File No. PRE26-000109 FROM: Alex Morganroth, Principal Planner SUBJECT: Lindbergh High School Phase 2 Modernization and Tennis Court Improvements 16426 128th Ave SE (APN 2823059004) General: We have completed a preliminary review of the pre-application for the above-referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision -makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available online at www.rentonwa.gov. Project Proposal: The applicant, the Renton School District, is proposing various interior and exterior improvements at the Lindberg High School campus. The existing high school building is approximately 241,496 sq. ft. in size and is located on a 37.25-acre site at 16426 128th Ave SE (APN 2823059004). The parcel is zoned Residential-6 (R-6) du/ac and has a Comprehensive Plan Land Use Designation of Residential Medium Density (RMD). Interior improvements proposed include seismic upgrades, mechanical and electrical improvements, and miscellaneous architectural work as needed. Exterior work proposed includes resurfacing the existing tennis courts, adding court lighting, retaining wall repair, repair of an existing storm line, and installation of a lit, concrete pathway connecting the pool building to the tennis courts. A “new service yard” abutting the gymnasium building is shown on the site plan abutting the gymnasium, but no info was provided regarding the equipment or screening for the yard area. According to City of Renton (COR) Maps, a high seismic hazard area and regulated slopes are mapped on the site. In addition, COR Maps has identified an offsite wetland on King County Parks property to the south. No trees are proposed for removal. The project would result in more than 5,000 square feet of new or replaced impervious surface. Current Use: The site is developed with the Lindberg High School campus, the associated surface parking, and various sport fields. Zoning and Overlay Districts: The area, including this property, has a Comprehensive Plan land use designation of Residential Medium Density (RMD) and is zoned Residential-6 (R-6) dwelling units per acre. The City’s Zoning Use Table Renton Municipal Code (RMC) 4-2-060 allows K-12 public institutions in the R-6 zone with a Hearing Examiner Conditional Use Permit. A Hearing Examiner Conditional Use Permit is required when changes in facilities exceed 10% of the development’s gross floor area. Based on the provided site plan and project scope the changes would not exceed the 10% threshold to trigger a Hearing Examiner Conditional Use Permit. The proposed improvements would not expand the uses at the subject site or substantially change the way the site is being used. CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 6 1. Development Standards: The project is subject to RMC 4-2-110A, “Development Standards for Residential Low Density and Medium Density Zones – Primary Structures” effective at the time of complete application (noted as “R-6 standards” herein). Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-6 zone is 7,000 square feet. Minimum lot width for interior lots is 60 feet. Minimum lot width for corner lots is 70 feet. Minimum lot depth is 90 feet. The existing lot appears to meet the minimum standards for lot size, width, and depth, and no changes to the lot are proposed. Building Setbacks – Setbacks are the minimum required distance between the building footprint and the property line and any private access easement. The required setbacks in the R -6 zone are 25 feet for the front yard, 25 feet for the rear yards, secondary front yard for c orner lots would be required to have a 25 foot setback, and interior side yards are required to have a combined 15 -foot setback with not less than 7.5 feet on either side. According to the applicant, no new buildings or additions to existing buildings are proposed. No changes to the existing buildings are proposed. Building Standards – The R-6 standards allow a maximum building coverage of 40% of the lot area. The maximum impervious coverage in the R-6 zone is 55%. The allowed height of public facilities shall be determined through site plan review. Compliance with the building standards would be required to be demonstrated at the time of building permit review. 2. Landscaping: With the exception of critical areas, all portions of the development area not covered by structures, required parking, access, circulation or service areas, must be landscaped with native, drought-resistant vegetative cover. The minimum on-site landscape width required along street frontages is 10 feet and shall contain trees, shrubs, and landscaping. Street trees in the ROW planter will also be required. Landscaping may include hardscape such as decorative paving, rock outcroppings, fountains, plant containers, etc. Minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060, Street Standards. Street trees and, at a minimum, groundcover are to be located in this area when present. Street trees shall be planted in the center of the planting strip between the curb and the sidewalk at the following intervals; provided, that, where right -of-way is constrained, irregular intervals and slight increases or decreases may be permitted or required. Additionally, trees shall be planted in locations that meet required spacing distances from facilities located in the right -of-way including, but not limited to, underground utilities, streetlights, utility poles, traffic signs, fire hydrants, and driveways; such spacing standards are identified in the City’s Approved Tree List. Generally, the following spacing is required: i. Small-sized maturing trees: thirty feet (30') on center; ii. Medium-sized maturing trees: forty feet (40') on center; and iii. Large-sized maturing trees: fifty feet (50') on center. A conceptual landscape plan shall be provided with the civil construction application prepared by a licensed Landscape Architect, a certified nurseryman or other certified professional. Please be aware that frontage improvements will be required. Storm drainage facilities are required to comply with the minimum 15-foot perimeter landscaping strip on the outside of the fence unless otherwise determined through the site plan review or subdivision review process. Please refer to landscape regulations RMC 4-4-070 for further general and specific landscape requirements. Per RMC 4-4-070, the landscaping regulations are only applicable to additions that increase the gross square footage of a building by greater than one-third (1/3), other changes in the use of a property or remodel of a structure that requires improvements equal to or greater than fifty percent (50%) of the assessed property valuation. Based on the project scope submitted with the preapplication request, the improvements proposed would not trigger site-wide compliance with the landscape standards. 3. Significant Tree Retention: A review of COR Maps appears to show that there are mature trees on the site. If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 7 proposed to be removed, a tree inventory and a tree retention plan along with an arborist report, tree retention plan and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. The tree retention plan must show preservation of at least 30% of significant trees. Please refer to RMC 4-4-130, Tree Retention and Land Clearing Regulations for further general and specific tree retention and land clearing requirements. In addition to retaining a minimum of 30% of existing significant trees, each new lot would be required to provide a minimum of 30 tree credits per net acre. Tree credits encourage retention of existing significant trees with larger trees being worth more tree credits. TREE SIZE TREE CREDITS New small species tree 0.25 New medium species tree 1 New large species tree 2 Preserved tree 6 – 9 caliper inches 4 Preserved tree 10 – 12 caliper inches 5 Preserved tree 13 – 15 caliper inches 6 Preserved tree 16 – 18 caliper inches 7 Preserved tree 19 – 21 caliper inches 8 Preserved tree 22 – 24 caliper inches 9 Preserved tree 25 – 28 caliper inches 10 Preserved tree 29 – 32 caliper inches 11 Preserved tree 33 – 36 caliper inches 12 Preserved tree 37 caliper inches and greater 13 Protected trees within a subdivision shall be retained in the order of priority listed in RMC 4-4- 130H.2. Protection of trees or groves by placement within a dedicated tract (Tier 1) is the highest priority. Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their associated buffers; significant trees over sixty feet (60') in height or greater than eighteen inches (18") caliper; and trees that shelter interior trees or trees on abutting properties from strong winds, which could otherwise allow such sheltered trees to be blown down if removed. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non-native trees. CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 8 Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. The Administrator may require independent review of any land use application that involves tree removal and land clearing at the City's discretion. The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that replacement requirements in RMC 4 -4- 130H.1.e can be met. Tree retention standards shall be applied to the developable area, as defined in RMC 4-11-040, Definitions D, of a property. If trees are proposed for removal, a formal tree retention plan and tree retention worksheet prepared by an arborist or landscape architect would be reviewed at the time of the land use application. 4. Fences/Walls: If the applicant intends to install any fences or retaining walls as part of this project, the location must be designated on the landscape plan and grading plan with top of wall and bottom of wall elevations. A fence and/or wall detail should also be included on the plan. A retaining wall that is 4 feet or taller, as measured by the vertical distance from the bottom of the footing to the finish grade at the top of the wall requires a building permit. The maximum height of any fence or retaini ng wall is 72-inches subject to further height limitations in setbacks and clear vision areas noted in RMC 4 -4- 040D. A fence shall not be constructed on top of a retaining wall unless the total combined height of the retaining wall and the fence does not exceed the allowed height of a standalone fence. Retaining walls shall be composed of brick, rock, textured or patterned concrete, or other masonry product that complements the proposed building and site development. There shall be a minimum three-foot (3') landscaped setback at the base of retaining walls abutting public rights-of-way. Please refer to retaining wall standards (RMC 4-4-040) for additional information about fences and retaining walls. No new fences or retaining walls were shown on the submitted materials. For more information about fences and retaining walls refer to RMC 4-4-040. 5. Access: Access to the site would not be changed as a result of the project. Access is currently provided via three (3) driveways off of 128th Ave SE. 6. Parking: Parking for vehicles, loading areas, and driveways shall be provided in accordance with the provisions of the current parking regulations of RMC 4-4-080, “Parking, Loading, and Driveway Regulations.” Parking requirements for senior high schools (public, pr ivate, and parochial) include a minimum and maximum of 1 per employee plus 1 for every 10 students enrolled. In addition, if buses for the private transportation of children are kept at the school, 1 off -street parking space shall be provided for each bus of a size sufficient to park each bus. No changes to the existing parking lots are proposed and no increase in use intensity is proposed. 7. Critical Areas: According to COR Maps, a high seismic hazard and regulated slopes are present on the site. Steep slopes (greater than 40% grade) require a 15-foot (15’) structure setback. No work is proposed within 15-feet (15’) of the top of the slope. A geotechnical report prepared by a licensed professional may be required by the Building Official at the time of building permit application submittal. In addition, four (4) wetlands are mapped on the site according to a wetlands report submitted in 2022 as part of the Lindbergh High School Modernization and Additions project (LUA22 - 000206) as part of a site plan review. The Wetland Rating Update prepared by Theresa R. Dusek and dated December 30, 2021 delineates and assigns ratings to the four (4) wetlands on the site (Wetlands A, B, C, and D). Wetland A CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 9 Wetland A, located south of the existing pool building, is classified as a Category IV palustrine emergent wetlands with a habitat score of three (3) and a total on-site area of approximately 0.12 acres. The required standard buffer is 40 feet (40’) and the required increased buffer is 50 feet (50’). Wetland B Wetland B, located downslope of Wetland A between the pool building and outdoor track , is classified as a Category III palustrine forested wetlands with a habitat score of four (4) and a total on-site area of approximately 0.03 acres. The required standard buffer is 60 feet (60’) and the required increased buffer is 80 feet (80’). Wetland C Wetland C, located downslope of Wetland B adjacent to the outdoor track, is classified as a Category IV palustrine scrub-shrub wetlands with a habitat score of three (3) and a total on-site area of approximately 0.03 acres. The required standard buffer is 40 feet (40’) and the required increased buffer is 50 feet (50’). Wetland D Wetland D, located downslope of Wetland C directly south of the outdoor track, was reclassified as a Category III palustrine scrub-shrub wetlands with a habitat score of four (4) and a total on-site area of approximately 0.04 acres. During a site visit in 2021, the consultant found the wetland was bisected by an existing gravel path, essentially bisecting it from the nearby wetlands system. The gravel is proposed to be paved over with concrete as part of the modernization project. In addition, pathway lighting is proposed. The required standard buffer is 60 feet (60’) and the required increased buffer is 80 feet (80’). The proposal includes improvements within and adjacent to regulated wetland buffers, including resurfacing of existing tennis courts, installation of tennis court and pedestrian lighting, and replacement of an existing gravel pathway with a concrete pathway. Based on the materials provided, these improvements appear to occur within previously developed and disturbed portions of the site, in proximity to Wetlands A–D, which are identified as Category III and IV wetlands. As such, the proposal is subject to the City’s critical areas regulations in RMC 4-3-050 (Wetlands), including buffer protection standards and the requirement to achieve no net loss of wetland functions and values. Several components of the proposal may qualify as allowed activities within wetland buffers, specifically those related to the repair and maintenance of existing legally established uses and structures, consistent with RMC 4-3-050C.3. The resurfacing of the existing tennis courts, where no expansion of the footprint is proposed, would be considered normal maintenance and may be permitted without mitigation, provided best management practices are implemented to avoid temporary construction-related impacts. Similarly, installation of lighting within already developed athletic and circulation areas may be considered a minor modification within a previously disturbed buffer area, subject to demonstration that impacts are avoided or minimized. The proposed pathway improvement, which includes replacing an existing gravel path with a concrete surface, may increase impervious surface area and alter stormwater characteristics. While this improvement occurs within an existing disturbed corridor, it will be required to demonstrate that impacts to wetland buffer functions are avoided or minimized to the maximum extent practicable. The applicant will be required demonstrate that there are no feasible alternatives outside the buffer, and that the proposal incorporates design measures (e.g., pervious materials, stormwater controls, light mitigation) to maintain pre-existing hydrologic conditions. Overall, the proposal does not appear to necessitate a Reasonable Use Exception or buffer reduction, but will need to comply with RMC 4-3-050, including preparation of supporting documentation demonstrating avoidance, minimization, and consistency with a no net loss standard. The applicant should also provide a detailed critical areas report identifying wetland boundaries, buffers, existing disturbance limits, and the extent of proposed improvements within buffers. Additionally, lighting CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre-Applications\2025\PRE26-000109 10 should be designed to minimize spill and glare into adjacent wetland areas, and all work should be conducted in a manner that protects existing vegetation and avoids further buffer degradation. A lighting a photometric plan will be required as part of the land use submittal. It is the applicant’s responsibility to ascertain if any other critical areas or environmental concerns are present on the site during site development or building construction. 8. Lighting: Stadiums, parks, and sports fields are exempt from the lighting regulations in RMC 4-4-075. However, careful consideration of the lighting design shall be taken in order to avoid light and glare impacts to neighboring residential properties. 9. Environmental Review: Based on the scope of work, the proposal appears to qualify for a categorical exemption under WAC 197-11-800(3) for repair, maintenance, and minor modification of existing facilities. The resurfacing of existing tennis courts and associated site improvements occur within a previously developed school campus and do not appear to expand the existing footprint of development. While portions of the proposal are located within regulated wetland buffers, SEPA exemptions may still apply where the proposal does not result in probable significant adverse environmental impacts. Final determination of SEPA exemption will be made at the time of formal application, and the applicant should be prepared to demonstrate that the proposal maintains existing conditions and does not result in increased impacts to adjacent wetlands or buffers. If the Renton School District is the lead agency, the threshold determination and appeal period would need to be complete before issuance of a building permit by the City. 10. Permit Requirements: A Critical Areas Exemption (CAE) for the work would be required. No fee is required for CAEs. CAEs can be reviewed in approximately 3-4 weeks depending on project scope complexity. CAE submittal requirements can be found here. A building permit and civil construction permit would be required as well. Detailed information regarding building and civil permit application submittal requirements can be found on the City’s Permit Services webpage. Other informational applications and handouts can be found on the City’s Digital Records Library. If the project includes retaining walls, fences, or outdoor storage areas, separate permits may also be needed. When ready to apply for permits, contact the City of Renton Permit Services at PermitTech@rentonwa.gov. Please note that the City requires electronic plan submittal for all applications. Please refer to the City’s Electronic File Standards. 11. Impact Mitigation Fees: Based on the project scope, no collection of impact mitigation fees are anticipated. 12. Next Steps: When the formal land use application materials are complete, the applicant shall contact the Alex Morganroth, Principal Planner at amorganroth@rentonwa.gov in order to apply. 13. Expiration: Critical Area Exemptions are valid for a period of two (2) years. Once the Building Permit has been issued, the Building Permit is valid for a period of 18 months from the date of issuance, unless an extension is granted by the Building Official. It is the applicant’s responsibility to monitor the expiration dates.
